FUNK MODEL 1213704NO TRANSMISSION (Continued)
Power is transmitted from an engine to the Revers-O-Matic Drive through the use of a torque converter. Being
no direct mechanical connection between power and load, a very smooth and shock-free drive is obtained with
complete absence of engine stalling and lugging. Consequently, the maintenance of axles, bearings,
differentials, and gears is reduced to a minimum. Another feature of torque converter drive is the automatic
multiplication of engine torque during the periods of heavy pulldown loads. When loads are light, the converter
transmits the engine power directly at almost engine speed without torque multiplication. With the output torque
automatically adjusting to the load demand, the net result is an action like a transmission with infinitely variable
and automatic speed ratios. The need for shifting gears, although present, is greatly reduced along with driver
Like all mechanical equipment, the Model 1213704N0 Revers-O-Matic Drive will need attention and servicing.
Routine checks will help prevent down-time. The operator can aid in preventive maintenance by occasionally
reading the instrument panel gauges and keeping a watchful eye; reporting weak or borderline malfunctioning.
Because the unit operates "IN" oil and "BY" oil, most of the maintenance is concerned with oil replenishment and
Rules of Maintenance
Check oil level daily, stopping engine before check. Make sure area around oil fill is clean before removing
dipstick. A drain cock or plug is provided on the oil fill side of the unit at oil level. If working conditions are
severe, it is recommended that the oil level be checked using the drain cock; that is, if oil starts to drip out when
opening the drain a proper oil level is being maintained. This method of checking the oil level is especially
desirable on units operating in mines, sand and gravel pits, etc. where it is highly possible to have foreign
material packed around the oil fill where it could fall into the unit when the dipstick is removed.
